Many practical situations experience what is called "non-normal" data. Practitioners dislike this because the tools to handle it are more complex and less understood by others. There are real and false causes of non-normal data, so we need to be confident in our determination. Non-normal tools tend to be less powerful than the standard tools, so care needs to be used to select the most powerful tool.

The next core area is "Remember." There are 3 schools of thought for DOE - Western Method, Taguchi and Shainin. Each has a strength for application with Box's tools being the most widely applicable. Remember the definition of DOE: A tool to assist in the process of understanding a system. And finally, DOE can generate predictive innovations. DOE is often used to resolve conflicts, but early use can help avoid major schedule delays.

I recently wrote a white paper regarding why the catapult is a poor tool for DOE training. Unfortunately, it is a common tool. If you want to learn about DOE and use it, avoid the catapult. If you want to find out why it is so bad, read this paper.

Videos and video briefs

Each brief has 3 videos to expand on various areas for each topic. Pick an area of interest and improve your understanding.

Project Execution Are the projects executed valuable? Here are case studies at various phases of the process.

Achieving Innovation Companies want to be creative and innovative. How can Design of Experiments help with that? You might be surprised.

Overcoming Development Challenges When a project experiences a challenge, what do you do? What should you do? We explore this topic - a key to successful New Product Development.

Program Management How can effectiveness be improved with New Product Development? What are keys to success.

Underused Product Development Tools When involved in new product development, we have no time for wasting time. What tools should we be interested in?

Training Effectiveness How do we create a valuable training program? How can we spot a bad one?

Our DOE Process - Decision Making Focus Too often Design of Experiments is presented as a series of tools. Instead, it is best used as a decision making methodology.

Achieving Robust Design Creating a Robust Design is of high interest. How can you make it happen? Can you do it cost effectively? We can provide a design or process that meets the level of robustness that you desire and maintain your schedule.
